ROLLER-COLTER AND JOINTER.

SPECIFICATION forming part of Letters Patent No. 357,848 dated February 15, 1887.

Application filed November 26, 1886. Serial No. 219,971. (No model.)

To all whom it may concern.-

Be it known that I, DEVVI'IT A. MOON, of Limona, in the county of Hillsborough and State of Florida, have invented certain new and useful Imp rovementsin Roller-Golters and Jointers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being bad to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in roller-colters and jointers; and it consists in the combination of the beam of the plow, the standard or colter bar, which has its upper end clamped to the beam, the shoe or gage which is pivoted to the lower end of the bar or standard, the roller-colter, and the j ointer, both of which are placed upon the shoe or gage.

It further consists in the combination and arrangements of parts, which will be more fully described hereinafter.

The objects of my invention are to provide a roller-colter for plows which will effectually sever the weeds or grass that may elogthe plow; to provide ameans for holding the rubbish, grass, or weeds while being severed by the colter; to place a colter and jointer upon the shoe, the colter in such relation to the jointer as to prevent it from being injured by rocks and stones, and the colter in such relation to the shoe as to bring its horizontal axis as near as possible to the surface of the ground or cutting-point, and the shoe capable of being adj ustedin any desired relation to the plow.

Figure 1 is a side elevation of a colter and jointer embodying my invention. Fig. 2 is a plan view of the same with the top of the journal-box removed. Fig. 3 is a detail view.

A represents the beam of an ordinary plow, to which the colter bar or standard B is secured by means of a suitable clamp. This clamp consists of the plates 0 D and bolt E. The plate 0 is provided upon its inner side with the two projections F, which limit its movement. These projections are preferably placed upon diagonal corners of the plate 0, the bottom projection coming constantly in contact with the under side of the beam A, while the upper one allows the plate 0 a partial rotary movement, and consequently the bar or standard B, which has the shoe G secured to it, a corresponding movement to the plate 0, thus allowing the shoe which carries the colter and jointer to follow any unevenness of the ground. The plate 0 is provided upon its inner side with corrugations, and the plate D with one or more projections, which engage the corrugations in the plate 0, whereby the plate D is capable of being adjusted as desired.

The plate D is provided upon its outer side with the recess H, in which the bar B rests. The securing-bolt E is provided with an eye at one end, through which the standard B passes, and its other end with a thread and nut for drawing the bar B tightly against the plateD and securely holding it into any position into which it may be adjusted.

The lower end of the bar B passes loosely through the front end of the shoe G, and is prevented from slipping out by means of a pin or nut. The shoe G is curved downward, as shown, a suitable distance, then having a fiat portion which rests upon the ground, and its rear end turned upward asuitable distance and the jointer H secured thereto in any suitable manner. Journaled directly over the flat portion of the shoe G is the colter I. The diflicultyin using roller-colters hasheretofore been that the horizontal axis being so far from the surface of the ground or cutting-point, when they came in contact with the grass or rubbish they had a tendency to pass over the rubbish instead of severingit. Byjournaling the colter, as here shown, the horizontal axis is brought very near the surface of the ground or cuttingpoint,and thus this tendency of riding or passing over the rubbish or grass is almost entirely obviated. Without this shoe attachment the plow at times would run too deep and at other times too shallow if the colter was made to run deep enough to cut horizontally with its axis to do good work. The shoe being curved, as shown, in front, forces the grass, weeds, or rubbish down upon the surface of the ground and holds it in contact therewith while it passes over it. The frictional contact of the rubbish or weeds with the ground being greater than with the under surface of the colter, the colter passes purpose of supporting the jointer at the point that it is attached to the shoe above the ground, so as to prevent the possibility of any rubbish being caught thereby, and thus clogging or interfering with the effectual operation of the shoe and colter. The rear end of the shoe being turned upward allows all rubbish to freely pass without in any manner obstructing the operation of the colter.

The jointer is secured to a brace or support, K, which is turned outward a sufficient distance for the inner edge of the jointer to just come flush with the outside of the colter. The brace or support is turned downward at its outer end, so as to form a sufficient hearing for the jointer to be securely fastened thereto. This brace or support K is detachable from the shoe, and hence can be readily removed therefrom, if desired.

The lower end of the bar or standard B is bent, as shown, so as to form an eccentric by means of which the shoe can be adjusted nearer to or farther from a vertical line with the side of the beam. By bending the lower end of the standard or bar B, as shown, the barB and its attachments can be secured to the beam of any plow, and adjusted in the desired relation to the plow by turning the bar B, which will cause the front end of the shoe to be brought nearer to or carried farther ,from the beam.

The colterl is detachably secured to the hearing L, at its outer end, for the purpose of allowing a larger or smaller colter to be placed thereon, according to the condition of the land in which it is being used. If the soil is loose, a large blade will work better, while if the soil is stuff or sandy a medium-sized blade would be desirable; but if the soil were stony the smallest-sized blade would work to the best advantage. The lower edge of the colter eX- tends below the j ointer a suitable distance,-for the purpose of protecting the jointer from any damage which might occur to it by striking rocks, stones, or large roots. Should a large stone or root be encountered, the lower edge of the colter will strike it and ride up over it, raising the shoe and with it the jointer. If the lower edge of the colter were not made to extend below the j ointer, the jointer would have no protection whatever, and would gather all roots under the surface below the lower edge of the colter and be damaged by stones or roots, to which it would be constantly suhj ected. Thus it will be seen that the jointer is tlioroughly protected from any damage by coming in contact with large stones, rocks, or roots, to which jointers are constantlysubjected when used in connection with colters which have their lower edge above the bottom of the jointer in the usual manner. The outer side of the colter coming against the inner side of the j ointer forms a landside for the colter, and prevents any side draft.

The journal L is provided at its inner end with a head, N, a suitable bearing-surface, O, and a shoulder at its outer end. The shoulder M is made larger on its outer side than its inner, thereby forming a sand-box or cavity into which all the sand or dust which may work into the bearing will be deposited. The journal-box on its outer side is made flaring outward, the inside fitting closely to the pinion,

so that sand passing between the outside end of the sandbox and the washer, against which the inner side of the colter bears, will not be forced through into the cavity. By having the outer side of the journal-box flared outward, as shown, sand and dust will not be forced through into the bearing, for the reason that all crowding of the sand and dust between the washer upon the inner side of the colter and the outer side of the box is prevented.

It will be readily understood that the shoe G could have its front end lengthened and pass upward a sufficient distance, to be passed through the eye of the bolt E, and thus do away with the standard B entirely. This would not be preferable, however, for many reasons. By using this shoe attachment all weight is removed from the animals back, which comes upon the shoe, thus preventing sore backs and galling.

Having thus described my invention, I claiml. The combination of the beam, the shoe or gage secured thereto, and the colter which is journaled upon the shoe, for the purpose set forth.

2. The combination of the beam, the standard or bar B, the shoe pivoted at its front end to the lower end of the bar, the colter journaled upon the shoe, and the jointer secured to the rear end of the shoe, substantially as shown.

3. The combination of the beam, the standard or bar B, bent at its lower end, the shoe G, pivoted upon the bent end of the bar, and the colter I, journaled upon the shoe, substantially as described.

4. The combination of the beam A, the standard B, clamped thereto and made movable in connection with the beam by means of the plates 0 D and eyebolt E, the shoe G, connected to the lower end of the standard, the jointer secured rigidly to the rear end of the shoe, and the revolving collar journaled upon the top of the shoe by means of the shaft L, provided with the head N and shoulder M, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
